The C++11 Standard (ISO/IEC 14882:2011) says in § C.1.1:
char* p = "abc"; // valid in C, invalid in C++
For the C++ it’s OK as a pointer to a String Literal is harmful since any attempt to modify it leads to a crash. But why is it valid in C?
The C++11 says also:
char* p = (char*)"abc"; // OK: cast added
Which means that if a cast is added to the first statement it becomes valid.
Why does the casting makes the second statement valid in C++ and how is it different from the first one? Isn’t it still harmful? If it’s the case, why did the standard said that it’s OK?
